Add "toggle comment" action to right-click context menu

This lets the user perform the action to toggle comments on or off for
the current line or the current selection in the code editor by
selecting "Code->Toggle Comment" from the right-click context menu.
Previously this action could only be performed by hotkey (ctrl+/ by
default.)
